"I thank my Dad for paying for my treatment," Brandon wrote. "It's the best thing he has ever done for me. Today I am almost two years sober. Every day that goes by I feel ever more grateful. My clear mind has allowed me to do a lot with this time. So much so that I would like to offer to pay for his treatment."

“It's so sad that Tommy feels the need to keep attacking his son despite Brandon's pleas to quit their very public feud," the source says. "Brandon wants to rise above all of this but keeps getting pulled into it and defending himself.

“It has been very difficult for Pamela to watch the father of her children be endlessly toxic toward them," the source says. "She truly feels not only did Tommy abandon them, but he continues to be harmful."

"Despite the defamatory exchange between Brandon and Tommy, Brandon and the family still have hopes Tommy will finally turn his life around and get real help," the source adds.
